DUMPING-V'EHICLE Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed March 26, 1907. Serial No. 364,586.

T 0 all whom it may concern:

Be it known that I, JOHN W. KING, a citizen of the United States, and aresident of New York, in the county of New York and State of New York,haveinvented certain new and useful Improvements in Dumping, Vehicles,of which the following is a specifi cation.

My invention relates to improvements in dumping vehicles, particularlyto dumping cars.

It has for its object to provide means for "first positively slidingthe'body of the vehicle I l outlet 15 therefor, whereby the pistons 16horizontally and allowing it to be dumped at the end. of its horizontalmovement by the momentum imparted to it in its sliding' moy'ement,without further movement of or aid from the means for sliding it, andafter it has been dumped, to positively return it to its horizontalposition and sliding itover to its normal osition.

It has or a further object to rovide means for locking the body of theve iicle in its normal horizontal position, ada ted to be automaticallyunlocked, by the b0 y operating means in its movement before beginningto slide the body of the vehicle.

It has for a still further object to provide means of the character setforth embodying advantages in point of perfectoperation and simplicityand inexpenslveness of construction.

In the drawings, Figure 1 is a side view of 'vehiele, showing my bodyoperating and locking means app led. Fig. 2, a similar view, showing thebody dum ed and the consequent position assumed y my body operating andlocking means. Fig. 3, is a fragmentary detailview of my body operating.and locking means removed from the vehicle.

Like reference characters desi nate corres )onding parts in the figuresof t e drawings i ustrating my invention.

Referrin to the drawin s, 1 desi nates the body o the vehicle whic isprovi ed, at its ends with downwardly extending ortion 2, engaging andslidable on upwardly extending portion or rests 3, at the end of theunder frame 4, when the body is in its horizontal position. Also at itsends the body of the vehicle is provided with downwardly extendingframes 5 on which are pivotally mounted gravity 'arms or books 6 havincam noses 7 adapted, when the body of n13 vehicle is in its normalhorizontal position,

to engage the I-beam 8 formin the center sill of the under-frame and 100said body and when the body of the vehicle is slid horizontally previousto being dumped, to-be disengaged from the I-beam, by the means to bedescribed, and unlock the body.

Motive fluid cylinders 9 are secured by i brackets 10 to the ends of oneof the channel'- irons 11 which form the side sills of the under frameand said cylinders are provided at one end with an inlet 12 for themotive fluid and anioutlet 13 therefor and at the other end with aninlet .14 for the motive fluid and an of the cylinders are adapted to berecipro-' cated.

The outer ends of the piston-rodsl? are provided with cross heads 18 towhich the Inner ends of plates 19, forming links, are pivoted by pins20, the other ends of sald )lates being pivoted by pins 21 between theforked ends of U-shaped arms 22 secured on a shaft 23 journaled on thechannel iron 24 which with the I-beam 8 forms the center sill of theunder frame.

'On the ends of the shaft 23 are secured U-shaped arms 25, the ends ofwhlch em brace and are loosely pivoted to the, lower ends of arms 26, bypins 27 en aging and slidable in elongated slots 28 therein, the upperends of said arms 26 being pivoted to the frames 5 by pins 29, therebyproviding for a slight degree of independent movement of the arms 25,before they transmit movement to the body of the vehicle, for thepurpose of bringing the cross pieces 30, connecting said arms, intoengagement with'the cam noses of the gravity arms 6 and raising saidarms out of engagement with the I-beam 8 to unlock the body From theabove escription considered in connection with the drawin s, it will beapparent that upon motive uid, preferab y air, being admitted into theinlets 12 of the cylinders, the pistons and their rods will be forced.to the left and through their connection with the arms 22 will turn theshaft 23, and thereby the arms 25, first simultaneously sliding the pins27 to the left in the slots 28 of the arms 26 and moving the crosspieces 30 under the noses of the gravity arms 6 and raising said armsout of engagement with the I-beam 8 of the under frame which unlocks.

the body, and then ositively moving the body to the end of 1tslongitudinal movement, whereupon the momentum imparted to the body willcasue it to dump and in dohook and unlock the body previous to iming soslide the arms 26 to the left on the pins 2 27, and that upon motivefluid being admitted into the inlets 14 of the cylinders, the pistonsand their rods will be forced to the right, and through their connectionwith the arms 22 will turn the shaft 23 and thereby the arms 25positively moving the body of the car back to its normal position. andcausing the cam noses of the gravity arms 6 to ride upon the I-beam 8and the hooked ends to engage the I-beam and lock the bot y.

I do not wish to be understood as limiting myself to the precise detailsand arrai1gements of parts shown and described, but reserve the right toall modifications within the scope of my invention.

Having now described my invention what i I claim as new and desire tosecure by Letf means actuated by said pistons, adapted to ters Patent,is

1. In a vehicle, a supporting frame, a

dumping body thereon, means adapted to i automatically lock the body innormal position and means adapted to unlock the body previous toimparting movement thereto,

parting movement thereto, positively move it horizontally and allow itto dump of its own momentum and then positively return it to normalposition, substantially as described.

4. In a vehicle, a supporting frame, a dumping body thereon, meansadapted to automatically lock said body in normal position, fluidactuated pistons and means actuated by said pistons adapted to unlockthe body previous to imparting movement thereto, positively move ithorizontally and allow it to dump of its own momentum and thenpositively return it to normal position, substantially as described.

5. I11 a vehicle, a supporting frame, a dumping body thereon, a gravityhook adapted to automatically lock the body in normal position, fluidactuated pistons and unlock the body previous to imparting movementthereto, positively move 11, horizontally and allow it to dump of itsown momentum and then positively return it to positively move ithorizontally and allow it i to dump of its own momentum and thenpositively return it to normal position, substantially as described.

2. In a vehicle, a supporting frame, a dumping body thereon, a gravityhook adapted to automatically lock the body in to imparting movementthereto, positively normal position and means adapted to engage saidhook and unlock the body previous to imparting movement thereto,positively move it horizontally and allow it to tially as described.

3. In a vehicle, a supporting frame, a day of March, A. D. 1907.

dumping body thereon, a gravity hook adapted to automatically lock thebody in normal position and having a cam nose and means adapted toengage the nose of said normal position, substantially as described.

6. In a vehicle, a supporting frame, a dumping body thereon, a gravityhook adapted to automatically lock the body in normal position andhaving a cam nose,

fluid actuated pistons and means actuated by said pistons, adapted toengage the nose of said hook and unlock the body previous move ithorizontally and allow it to dump of its own momentum and thenpositively re turn it to normal position, substantially as described.
